Review comment:
I guess I was more thinking of the impact through `DataSegment.Builder()`
which with this change [will now create a new object in the
constructor](https://github.com/apache/incubator-druid/pull/6883/files#diff-93f2cf9022ac4126afc3ee5989f4f5bfR376)
to set the default before it is likely later replaced when the actual shard
spec is set before completing the build, instead of the previous behavior of
re-using the same object.
